St. John Chrysostom(c.347-407)
-
Archbishop of Constantinople. He is known for his eloquence in preaching
and public speaking, his denunciation of abuse of authority by both
ecclesiastical and political leaders.

"The saints are
exceedingly loving and gentle to mankind, and even to brute beasts ...
Surely we ought to show them [animals] great kindness and gentleness for
many reasons, but, above all, because they are of the same origin as
ourselves." .
